Funded by NSF BCS 1539687, “The Role of Frontal Cortex in Primate Metacognition” , PI Marc Sommer, Co-PI Jeff Beck.

The goal of the project was to establish how primates plan to make future decisions, a cognitive function known as metacognitive control. The research quantified the metacognitive capabilities of primates, the neural mechanisms involved, and the computational basis of the operations. Data for both papers available here.
